how fast is terminal velocity?

Answer 1

there is no set speed for terminal velocity. an object reaches its terminal velocity when the downward force of gravity equals the upward force of drag. it would all depend on the structure of the object. size, mass, density, aerodynamics, etc. would all go into the factor of terminal velocity. the possibilities to answer this question are endless.

Answer 2

Of course you can. Terminal Velocity is merely the velocity at which the drag you experience equals the driving force behind your motion. So, say if you are in a plane that is in free-fall and is accelerating at g = 9.8 m/s/s. Then, after a bit of time appropriate to the plane's cumulative mass, it will reach the maximum rate of velocity that it can get to. However, if the engines then kick on at some point soon enough to prevent crashing, then the new velocity set will be the speed previously had without the engines being on + the speed gained through the acceleration given by the engines being on. In that case, because terminal velocity is the velocity at which the drag force equals the propulsion force, then because the propulsion force is greater than before, the drag force must be greater as well if it hopes to cancel it out. SO, to answer your question, AYE. Terminal velocities are fluid just like anything else, and change according to the circumstances (minus light of course. haha xD)

Answer 3

The terminal velocity of an object depends upon its mass and it size and shape. For example, a feather has an extremely low terminal velocity, just slowly floating down to the ground. People wearing a parachute have a terminal velocity that is slow enough to allow them to land safely. Without a parachute a person's terminal velocity is more like 120 mph.

Answer 4

Terminal velocity varies directly with the ratio of drag to mass. More drag means slower terminal velocity. Increased mass means higher terminal velocity. An object moving downwards at greater than terminal velocity (for example because it was affected by a force downward or it fell from a thinner part of the atmosphere or it changed shape) will slow until it reaches terminal velocity

Answer 5

I thought terminal velocity for a human was 145MPH, Terminal velocity is that speed where the object cannot fall any faster due to wind resistance on it's surface, Isn't it??

Answer 6

there is no fixed value for terminal velocity.

Answer 7

about 120mph for a human. With arms to the sides, speeds of up to 200mph can be reached.
